TO ALL WHOM IT MAY CONCERN: j K

Be it known that I, HENRY R. HALL, of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Enamclling-ltiachinery; and I do hereby declare that the ffollowing is a full and exact description of the same, reference being had to the annexed drawings, and to the letters ot' reference marked thereon, in which drawings- Figure 1 is a perspective view ofthe machine, one corner being broken away to disclose the under gearing, a part of whichappears in red lines. l

Figure 2 is a vertical sectionon the line Jy of iigfl, the endless chain being removed to show thefbed-plates.

Figure 3 4is'a perspective view of a part of. the machine, showing a piece of moulding asit passes, by ythe action of the endless chains, ythrough the Scrapers, and showing also the springs by which the scrapers are enabled to adjust themselves tothe mouldings. l

, Figure 4 is a similar view of the guides or ways, against which the endless chains have a lateral bearing..

Figure `5 is a similar view of a portion of the endless chain, showing its dat links.

Figure 6 is asimilar view of the pinion-wheel.

Figure 'i is a vertical section of the pulley and of part of the stud upon which it turns v In fig. 1, a'represents the table by which the machine is supported. b b1 b2, figs. 1 and 2, are three separate bed-plates, the middle plate, b, being fixed to the table, and the plates b and b2'being movable to or from the ixed plate bi, to adjust the machinery to various sizes ofthe mouldings or other things-to be enamelled.

c el c2 are pulleys, turning respectively upon upright studs, d dl'c", which project from the bed-plates b Zi1 b2. e el eZ are pinion-wheels, fastened respectively to the upright shafts fffz, which have fastened on their lower ends the bevel-cog wheels g g1 g2, which gear into the similar wheels, h h1 h2, on the clrivingshaft z', whichl isv provided with feathers, j, which enter corresponding recesses in the wheels t 71,2.' The wheels i h2 are further secured, and wheel h1v is also secured to the shaft z' by set-screws, as shown. By removing their set-screws, the

wheels t h2 may be adjusted on the shaft z', tb correspond with any-adjustment of the bed-plates b bz, and'parts attached. 7c c k2 are endless chains, pnssngedgewisel around pulleys c che2 and pinion-wheels e) c1 e, respectively, havingltlat links, as shown, to feed forward the mouldings, and at the same time save them from indentations, and having lateral support against the guides or ways m m', gs. 1 and 4. The two plates, which con- I stitute the ways m m', are rigidlyattached by studs to the bed-plates b 11162 respectively. The middle and larger-portions of the sides of the ways m m' are parallel, andl the ends of said ways are rounded off, as shown, to allow the chains to be turned with more ease, and without indenting the mouldings or other things being enamelled. n n are thumb-screws, (abutting against 'springs 11,) by which the movable plates, b b2, and their respective chains, are set further-freiner nearerto the iixed-plate b1 and chain c, to suit the various sizes of mouldings, &e. o, figs. 1 and 3, is a hopper, such as is now generally employed in enamelling. The Scrapers w w constitute the ends of hopper o; I

I secure the hopper o to the table a by means of springs p, iig. 3. A similar hopper is placed at g, g. 1. Power is applied to the driving-shaft z'. The pinion-wheels `e el e2, being thus put in motion, give motion to the endless chains. The ends of the mouldings, zang. 3,01- other things intended to be enamelled, are introduced at r to the space between chains 7c and k1, and at s to the spacebetween chains c and 7c, and are fedA forward.l through the Scrapers w w. i

It is obvious that there are various-arrangements of springs, other than the arrangement shown, by which the hoppers and Scrapers may be made seltadjustable to the form of the mouldings.

It is also obvious that the chain-guides or ways'm m', instead of being composed of two platesv united by studs, as shown, might be cast in a solid piece, with its edges grooved out s uiieiently to prevent interference with the chains; or these ways might be composed of bars, attached to the bed-plates in any convenient manner,

the edges or faces ofthe bars presenting lines similar to the lines of the edges of plates m m.

Instead of employing the thr'ee endless chains kl k2, two only, as 7c kl, maybe employed, if desired, or

the number of chains may be increased indefinitely, the supporting-table a being enlarged, and the necessary running-gear, similar to that describedylbeing correspondingly supplied.:l v 1 Instead of attaching the Scrapers to the table by means of springs, as shown, they might berigidly fastcned to the table, or they might be entirely separate from the table,and applied to the mouldngs by thellands of an operator, or a single separate scraper might be thus applied. p

Having thus described my invention, I claim, and desire to secure by Letters Patent- 1. Making the hoppers and scrapers seliadjustablc by the application of springs shown and described. J

2. Feeding the mouldings er other objects to be enamelled through the Scrapers by means oi' endless chains set edgewise, and providedrwith iiat links to prevent indentation Vof the mouldings, substantially as shown and described.

8. Making the bcd-plates b and b2, both or either of them, with their chains or otherattached parts, adjustable relatively with the xed bed-plate l, its chain and other attached parts, to adapt the machine to the various sizes of mouldings or other objects to be enamelled, substantially as shown and described.

4. The endless chains c c, their respective ways or lateral bearings m m', and the mechanism for giving motion to said chains, in combination with. two Scrapers or a single scraper, substantially as shown and described,

for the purpose specified.
